C158 and C159 – Universally configurable AC and DC contactors up to 500 A

Single-pole and double-pole cam contactors (NO/NC) up to 1000 V rated insulation voltage and 500 A continuous current. Electric arc chambers for higher power ranges, blowout magnets for DC applications.

C159
Double-pole AC version
Conventional thermal current up to 500 A
Rated insulation voltage up to 1,000 V
Auxiliary Switch: 1x S826, 2x cam switching element S007

From the universally configurable series C158 and C159 result single-pole and double-pole contactors for AC and DC with cam switching elements of the S310 series for 500 A of continuous current.

The main contacts can be configured as make contacts, break contacts or as combinations of these. An electric arc chamber with permanent-magnetic blowout is available for the arc quenching at high DC loads.

The switch state of the main contacts can be reported to higher-level control systems and devices with up to 4 auxiliary contacts.

Features

Robust design, simple maintenance

The cam contactors C158 and C159 are designed for switching loads frequently. The switching elements can be replaced individually.

DC version with blowout magnets and arcing chambers

During switch off, an electric arc is ignited between the opening contacts. The current flows on through the ionised air. Permanent magnets drive the ionised air out of the contact zone into the arcing chamber. Here, the electric arc is extended and cooled until it goes out.

For DC voltages of up to 300 V, the S310 C cam switching element should be used: with permanent-magnetic blowout and optional electric arc chamber.

Unidirectional DC applications of up to 300 V DC

Single-pole and double-pole cam contactors C158 and C159 can be used in all DC applications up to 300 VDC in which the load does not have to be switched off in both directions:

  • Railway technology
  • DC drives of machinery
Economy resistor or optional electronic economy circuit

In order to protect the coil of the contactor from excessive heating, a resistor is connected in series with the coil after switch-on.

Optionally, an electronic economy circuit can be chosen. This supplies the required pick-up current for the activation. The current is then regulated down by the electronic economy circuit to the a significantly lower holding current. As a result, the coil becomes less hot and the control power is reduced considerably. The module is attached directly under the contactor.

Up to 4 auxiliary contacts in auxiliary switch blocks

The switch state of the main contacts can be reported to higher-level control systems and devices through auxiliary contacts.

Break contacts, make contacts or combinations of these are available with the cam-operated switching elements of the S007 series. For safety-related tasks, S800 or S826-series snap-action switches can be chosen: Changeover contacts with double-break contact and mechanical positive opening operation .

The auxiliary switch blocks are installed ex-factory. Quantity and contact type are to be specified during the order.
